A simple general-purpose I-V model for all operating modes of deep-submicron MOSFETs is presented. Considering the most dominant short channel effects with simple equations including few extra parameters, a reasonable trade-off between simplicity and accuracy is established. To further improve the accuracy, model parameters are optimized over various channel widths and full range of operating voltages using a heuristic optimization algorithm. The obtained results demonstrate only 1.28% and 0.97% average error in IBM 0.13um CMOS technology for NMOS and PMOS, respectively, comparing with the accurate physically-based BSIM3 model. Furthermore, the tolerance of the model accuracy against parameters variation is investigated.
